About surveillance in Azerbaijan
West Nile virus is the mosquito-borne disease with documented circulation in Azerbaijan, but no national human case count has been published. Azerbaijan reports outside the EU/EEA system (ECDC), so its surveillance falls to national authorities and the WHO Regional Office for Europe. The likely regional WNV vector is the common house mosquito (Culex pipiens); invasive Aedes mosquitoes have no published occurrence record in the country.
Frequently asked questions
What mosquito-borne diseases is Azerbaijan monitoring in 2026?
Mosticare tracks Azerbaijan surveillance for West Nile virus, each sourced to the responsible national authority or ECDC.
How many West Nile virus cases are reported in Azerbaijan?
No national autochthonous human West Nile virus case count has been published for Azerbaijan. The virus's presence in the country is documented in the scientific literature (reported as early as 1999), but Azerbaijan is not part of ECDC's EU/EEA surveillance reporting, and no recent figure from the national authority or the WHO Regional Office for Europe could be located. We therefore publish a qualitative circulation status rather than invent a number.
Does Azerbaijan have tiger mosquitoes (Aedes albopictus) or yellow-fever mosquitoes (Aedes aegypti)?
No published occurrence record places either species in Azerbaijan. A 2025 peer-reviewed review of Aedes mosquitoes in Iran and its neighbours found no evidence of Aedes albopictus or Aedes aegypti in Azerbaijan. Established invasive Aedes populations in the Caucasus are on the Black Sea coast (Georgia, southern Russia, north-eastern Turkiye), not the Caspian side where Azerbaijan lies.
Which mosquito spreads West Nile virus in Azerbaijan?
The principal regional vector of West Nile virus is the common house mosquito, Culex pipiens, which is widespread across the WHO European Region including the South Caucasus. It transmits the virus between birds and, occasionally, to humans and horses.
Is Azerbaijan in the ECDC West Nile virus surveillance data?
No. ECDC's weekly and seasonal West Nile virus surveillance covers EU/EEA member states and a defined set of neighbouring reporting countries; Azerbaijan is not among them. Surveillance responsibility lies with Azerbaijan's national public-health authorities, with the WHO Regional Office for Europe as the regional coordinating body.

About this data
Mosticare aggregates and re-publishes vector-borne disease surveillance from ECDC, EFSA, and national ministries of health. Mosticare is an aggregator, not a primary surveillance authority — every figure on this page cites the originating source and is independently verifiable. This is a partial aggregation; for the complete EU/EEA totals, ECDC is the primary source.
The data behind this page is published as free, machine-readable feeds under CC BY 4.0 — the point-in-time incidence snapshot at /threat-map/feed.json (JSON Schema) and the multi-year trends at /threat-map/feed/trends.json (JSON Schema). See the live Europe threat map and the full data room.
